Sounds borderline adequate. IDK much about mussels as a staple. It's an excellent food but does it have any shortcomings, like e.g., crustaceans? Anyone? I'd go with better pellets and non-fatty fish as a staple.

They're high in thiaminase, according to some sources. Other sources list them as a good source of thiamin. lots of protein, low fat and overall nutritionally pretty decent. I agree they aren't necessarily a great staple but they're good as part of a fish's diet.
 
Man those catfish are def no joke are they! I cant believe it can do that kind of damage to your midas in what 10 seconds you said?! Your def braver than me man i would be terrified to lose that terrific of a midas.

i know i wonder what im doing sometimes... i have a tank to split them if it goes south... i dont think he is capable yet though, midas gives as good as he gets...

other than what i have wrote he is pretty picky, only takes the odd prawn and doesnt take white fish fillets. suppose i could try massivore but its ssooooo expensive here in the uk! we havent got many options that im aware off.

The cheap ones are 'jmc' catfish pellets, they are what my lfs use. they contain; oil 11%, protein 47%, ash 12%, fibre 2%, phosphorus 2%, and copper at 3mg/kg.

Im guessing he was brought up on them, its been hard getting him to take anything but tbh... Obviously they wouldnt get them in the wild, probably crustaceans and whole fish as their natural staple. Maybe i should get some silversides, Does it make any difference feeding white sea fish i.e haddock fillets, cod, or maybe even mackeral or is that fatty? if i could get him on it. tilapia is rare here...

anyone recommend a good pellet here in the uk?

these any good?

I know its wrong but gave him a tiny piece of roast beef today, he mouthed it spat it and literally shook his head... this fish is epic!-)

My 4 wyckiis were quite unfussy (3" to ~6"), gobbled up any and all foods. My two 1'-1.5' would never come out for feeding in a 4000 gal pond (I suspect that they never came out at all or very, very briefly because of the aggressive ~2.5' TSNs and RTCxTSNs on constant patrol) but whatever I put in their clay pots appeared to have been quickly eaten.

IDK if it's an option, but I'd expect a 1-2 week fast would break them easily.

Mackerel is a cold water marine fish that is too fatty to account for more than ~20%-30% of the diet of a tropical predator, IMO. Arapaimag uses it regularly as a minor staple component.

Exactly as stated above: no ingredient list and too much fat - 22%. The usual fat content does not exceed 10%, even for a temperate water catfish, like channel, bullhead, wels.

If you overlook the unpleasantness, this could provide some good info on fish nutrition http://www.planetcatfish.com/forum/viewtopic.php?f=2&t=38692&hilit=+nutrition Note that RD. is one of the MFK leaders and everyone would be well advised to read his articles published here on MFK.
 
thanks dude my head is gonna pop lol!-) this is worth putting forward from the second link cheers!

India appears to make the best fish food. Check out this one called scampi food, middle-to-bottom of the page, and read the ingredient list: http://www.planetcatfish.com/forum/viewtopic.php?f=9&t=37166&hilit=+scampi

Balaji (aka Shovelnose on PCF) tells us they have pellets with 50%, 60%, all the way to 95% aquatic-derived protein pellets. I am ignorant but I imagine this is great for predators as one of the staples.
 
the farm made aqua feed??? seems to have maize and flours which are bad according to the last link!-)
 
One has to understand the quantities. If the pellet is 80%-90% protein and the wheat is mostly starch, the pellet can't have much of the wheat but very little, as opposed to the cheap pellets consisting of 80%-90% of wheat and/or corn -derived products. NLS uses wheat flour as a binder and the pellets contain a lot of wheat. RD argues that this is not bad at all for omnivores and herbivores but there is definitely room for improvement for carnivores=piscivores but the price becomes indigestible, AFAIU his point.

Clay uses egg white for binder = pure protein. RD is all for it and AFAIU thinks it is nice. What ticks him though are Clay's wide-sweeping claims that wheat etc. are bad as well as many other unsupported statements.

Anyway, can't lump all (cat)fish in one category. Can't do the same to the pellets. Wyckii is a predator. It hunts fish and crustaceans. Simplistically, I imagine his diet is ~90% protein as far as the solids and excluding water.

Predators have short digestive tracts that will not digest even aquatic hydrocarbons well, not to mention the terrestrial. Cheap pellets offered to an outright predator hurt their health in the first place and in the second mostly go through the fish undigested and pollute your tank water.

Omnivores have medium tracts. Herbivores have long tracts to handle hard-digest plants, as in part can be judged by how far the anus is from the stomach.

In fact, and this blew me away, omnivorous cichlids have been shown to lengthen their tracts in response to more plant-derived diet during certain times of year or in a lab and shorten it when fed more animal-derived diet.
